A team of physicists and engineers out of the University of California at Davis are taking the iPhone 4 to new heights--and they're not talking about No. 5.
Using materials that cost about as much as a typical app, they tricked out an iPhone with a few new tools, including a microscope, which--with the phone's camera--could identify features as small as 1.5 microns. That's small enough to identify different blood cell types.
"Field workers could put a blood sample on a slide, take a picture, and send it to specialists to analyze," says Sebastian Wachsmann-Hogiu, a physicist at the Center for Biophotonics, Science and Technology and lead author of the research to be presented in mid-October at the Optical Society's Annual Meeting in San Jose, Calif.
In rural clinics in developing nations, which tend to have limited if any lab equipment, these decked-out iPhones could help nurses and doctors diagnose a range of blood diseases by not only imaging blood cells but sending data in real time to colleagues anywhere around the world for further analysis.… Read more
